Heat the oil in a skillet and add the patties to it; cook over medium heat for 5 minutes.

Add the teriyaki sauce mixture to the skillet and carefully turn patties over; cook until the internal temperature of the thickest part of the burger reaches 160°F (70°C), about 3 minutes.

To serve, place one patty on the bottom half of each bun and top with a tomato slice and spinach. Top the burger with the other half of the bun.
